OSCAR MAYO, OF EVANSTON, ILLINOIS.

I'M PROVEM ENT IN LAM P-WICKS.

Specification forming part of Letters Patent No. 202,358, dated April16, 1878 application filed January 4, 1878.

To all whom it may concern:

Be it known that I, OSCAR MAYO, of the town of Evanston, in the countyof Cook and State of Illinois, have made new and useful Improvements inWicks for Oil Lamps, Stoves, &c., of which the following, taken inconnection with the accompanying drawings, is a specification.

My improvements relate to wicks which are in two contiguous sections,the one more or less indestructible, and the other a permanent conductorof oil thereto.

My object herein is to obtain a wick or tip of a trifling cost thatshallbe comparatively incombustible and indestructible, witlD certainconvenient tubes and attachments for operating same, as will more fullyhereinafter appear.

My invention consists in the use of paper wicks or tips prepared bygiving them a bath in a strong solution of salt, drying, and giving thema second bath in a full solution of equal parts of the phosphate andtungstate of soda, (which process is made the subject of a separateapplication by me for Letters Patent,) which paper tips of the wicks, intwo sections, areattached,byathinmetalplatehaving teeth along its upperand lower edge, to ordinary cotton, wool, or felt wicks, such as areordinarily used for conveying the oil from the fonts to the tips.

Referring to the drawings, Figure 1 shows the paper tip A attached tothe wick B by the inside metal tube B, having perforations d d d, thetip being made (as I prefer, for the purposes of more perfectcombustion) of two pieces of separately-prepared paper, each of the width and half the thickness of the wicktube to be fitted, which insidetube is of the same length as the outside tube, in which it operates,and has a shoulder, D, which prevents its being raised above the outsidetube. By this arrangement of tubes-the inner one moving with the wick,and the other one remaining stationarybefore the flame is extinguished,the wick is lowered inside of the outside tube, which prevents the wickfrom discharging the oil which it holds when not in use upon the outsideof the burner, which arrangement adds materially to the safety ofoil-burners. I do not restrict myself in this arrangement of tubes totheir combustion of wicks of two sections.

Fig. 2 shows the paper tip A attached to the wick G by a thin metalplate, I), having teeth 0 c 0 along its upper and lower edges, fastened,respectively, into the tip and the wick, the upper ones being shorterthan the thickness of the tip, so that the tip can be easily disengagedand replaced, the lower one being longer than the thickness of the wick,and clinched on its other side. By this arrangement for attaching thetwo sections of the wick, it can be prepared and sold in market for theordinary sizes of burners now in general use, without making a specialburner having reference to special-sized tubes and caps for thistip-wick. It is evident that the wick and tip can be sewed together attheir ends, as shown by Fig. 3, or attached by any of the otherwell-known means.

Fig. 4 shows an ordinary lamp-burner with the chimney and cap removed,having the paper tip and the wick applied, as shown in Fig. l.

I prepare the same for Argand burners by pressing the paper beforedrying after each bath on the form of the inside screw of the doublewick-tube of the Argand burner, the wick thus made retaining its shape,and, in practical use, not tearing itself away from its attachment byraising or lowering, as does the ordinary wick oftentimes in Argandburners.

No other preparation or change in the above paper tip or wick isnecessary to adapt it to a stove or other apparatus for producing lightor heat from oil or other burning-fluid than to vary the size and shapeof the prepared paper.

I am aware that prepared asbestus and other materials have beenheretofore used for oil wick tips.

Some of the special advantages of the paper wick or tip above describedare, that it will give a larger, whiter, and purer flame than the othermaterials mentioned, (the tips being of the same size 5) is very muchmore economical; will last as long or longer; being more pliable, iseasier of attachment and adjustment; and, like the other materials,enables the lamp,stove, &c., to be used for an indefinite period withoutthe trouble, annoyance, terial, the parts being united by plate I),havand expense of trimming the Wicks daily and ing the fasteningpointsc, substantially as and changing them every few days. for the purposeset forth.
